Having witnessed his son Charlie Jr. race both in Toyota Atlantics and the Champ Car World Series at Portland International Raceway, I was unaware that it was the elder Zwolsman who was responsible for resurrecting ‘Heinz 57’s (Heinz-Harald Frentzen) motor racing career – by having him race for the Minnowesqe Euro Racing Team in the World Sports Car series, (WSC) hiring Frentzen to drive for him at Le Mans way back in 1992.
